Catalans are quite OK with Gibraltar being British. In fact, during the war of succession that lead to Catalonia losing its political independence, the Catalans and the Brits fought on the same side (with the latter eventually deserting the former who decided to continue the fight on their own).
I recall the town of Girona's official website used to be http://ajuntament.gi/ (still works, in fact. Now redirects to their .cat domain), with .gi being, of course, Gibraltar's ccTLD. This was done before the launch of .cat when many Catalan businesses and institutions avoided the use of .es like the plague. The fact that it used to be a royal pain to register a .es did not exactly help the centralist cause either.
